wINn-surr LYINo APPARATUS For. MUSICAL INSTRUMENTS AND MUSICAL INSTRUMENT PLAYERS.

Application filed February 26, 1908. Serial No. 417,851.

To all whom it may concern.

Be it known that I, JAMES CLARKE HAGEY, a citizen of the United States, residing at Chicago, in the county of Cool: and State of Illinois, have invented new and useful Improvements in Find-Supplying Apparatus for Musical Instruments and h/Iusical- Instrument Players, of which the following is a specification.

My invention relates to musical 1nstruments such as organs, pianos supplied with automatic player-devices and to devices for automatically playing musical instruments and particularly concerns the apparatus comprised in instruments of this k nd for supplying and maintaining the desired degrees of operating air-tension or pressure.

The object of my invention is to provide apparatus which may be easily secured in 'or removed from operativeposition within the case of the instrument and to eliminate the troublesome connecting or disconnectingoi delicately adjustable parts usually experienced as a part of this operation. i Another ob'ect of the invention is to provide a construction that will permit inspection and adjustmontof practically all of the parts without necessitating removal of other parts to gain access thereto.

Further objects and advantages of my invention will be described hereinafter.

Figure 1 is a front view of the lower part of a piano showing my improved windsupplying apparatus in position below the key-bed;

Fig. 2 is an eniarged front view of the opposite end parts of the apparatus shown in Fig. 1, the greater part of the central sec tion being broken away as are also other parts to reveal the arrangement of the underlying windways and valves;

Specification of Letters Patent. Patented Nov, 20, 191 7,

I haveshown and will describe my inven- 31:.

tion as applied to a piano, positioned within the case thereof, andadapted to produce wlnd tension, but it Wlll be understood by those conversant with the art that the following descrlption will be equally applica- 1' ble to the apparatus when'installed in other kinds of musical instruments or' automatic player-mechanisms contained within separate cases and may be converted to supply windunder pressure withoutdeparting from F the spirit or scope of my invention.

1 designates the key-bed, 2 the sides, 3 the toe-blocks, 4: the toe-rail, lithe bottom, 6 the sound-board, and 7 the lower front panel of a' piano provided with automaticfi.

player-devices located in this instance above the key-bed and not shown.

Iprefer to rigidly support parts whichl shall term the tension-regulatingand controlling section of my lmproved apparatus upon. the under side of the key-bed land to include among such parts the devices clirectly-connected with and" controlling thewindways of the said apparatus. These devices are delicately adjusted and should not be disturbed or disarranged under the usual circumstances. I refer to the tension regulators or governors and to'the valveboxes; the latter being usually connected by accurately adjusted mechanism with parts i located in, upon,'or above the key-bed.

Such parts as under usual circumstances it may'benecessary to remove I prefer to support individually in the lower part of the instrument and connect by flexible means i with the parts hereinbefore described as rigidly supported upon the under side ofthe key'bed. Theseparts I shall term the tension creating and maintaining sections.

I provide vertically arranged support braces 1e and 14 at each side of the center of the instrument and supportblocks 15 and 15 between each of the braces and the ad.- jacent side 2 of the case. These braces and tom 5 of the instrument and present inclined surfaces at their forward edges which may be facedwith felt or other noise-preventing Their lower, parts may extend blocks are secured in position upon the botmay be provided in. some-other manner With supports to form cradles in which are placed the reservoir-chambers 1G and 16*. For the purpose of supplying rigidity to the apparatus as well as to the bottom 5 and toerail 4 which are sometimes materially weakened by'cutting away parts to accommodate the pedal connections, I extend the braces 145 and 1 1 upwardly to the under side of the'key-bcd 1 and secure them thereto. As demonstrated by F igp2, the chamber 16 is supported near its lower outer edge upon blot-1:515 and near its entire inner edge by the brace 11- and chamber 16. is supported -neariitslower'outer edgeupo'n block 15 and near 1ts entire inner edge by the brace 1%.

These rcserv0ir-chambers 16 and 16 are composed of similar parts arranged laterally in reverse relative positions and a description of one of the chambers will suffice. The chamber 16 is a shallow, rectangular, air-tightbox formed of a frame 16" and front and back sides 16 and 16 respectively. The members of the frame are sufliciently wide to embrace screws that may be passed through from the front of the chamber (as. at 38, Fig. 2) forthe purpose of securing it in position upon the support brace 14 and block 15. Bolster-blocks may be secured: in the air-space between the two sides 16 and 16, one of such being shown at 16. The front side 16 is provided with apertures 16 which open into a reservoir of any desirable type placed upon the outer face ofjthe side and of which I show a preferred construction comprising a movable side lti having an opening therein fitted with a cover or"bung 16, the removal of which will allow access to the interior of the reservoir and the expanding springs 16". Two other apertures are located at the upper part of the side, one of which 16 for communication between the chamber and the central pumping section and the other, which is positioned under and concealed by the nipple 17, is for communication between the chamber and the chamber access to the lower part of the piano plate and strings. The foi-indation-board 19 supports upon its'rear side pump-bellows having movable sides 11 hinged to swing upon their upper edges and provided with valveports 11 and exterior valves 11. Connected with the loweredges of each movable side is an arm 10 through which operating power may be applied by a suitable treadle mechanism, I have shown the type of treadle construction I prefer to use in. Fig. 5 wherein the swinging forward of the partially dis connected central section has caused the treadles to assume the position relative thereto which exists when the section is cor rectly connected and the treadles folded for concealment within the case. The opening in the front panel 7 may be made wide enough to permit remo *al of the section as is the case in Fig. 5 or. reduced to allow passage" only of the trcadle mechanism, which when unfolded in front of the apparatus assumes the position shown in Fig. 1. The treadle-supporting frame is pivoted at (a, to the board 19 and the treadlelinks 9 are pivotally connected with the arms 10. The springs are retained in position to oppose the rearward movement of the sides 11 by means of the arms 1:2 which are formed by bending upward and providing with screw-holes the end parts of flat strips of metal. One end of each of the arms 12 is then screwed to the front of the board 19 and the inside face of the other upturned end fitted with a block secured thereto and provided With a transverse slot for recep- 'tionv of the prongs cf the spring 13. Along the upper edge of the board 19 I arrange and secure thereto a horizontal conduit or trunk 20, closed at the ends and extending laterally beyond the board and partially reaching over the front of the reservoirchambers 16 and 1G. The rear side of this trunk is provided with series of ports as at 21, 21 and 22, 22. Each of the series of ports 21 extends completely through the board 19 and open out into the interior of one of the pump-bellows and valves 23 are arranged upon'the rear surface of the board over the entrance of the ports into the said bellows. Ports 22 (Figs. 2', 1 and 8) are each positioned to register when the section in operable position with the apertures 16 in the reservoir-chambers.

Close to the inner edge of the front side 16 of each of the chests 16 and 16 and placed preferably at a height that will permit the forward swinging of the central section demonstrated in Fig. 5, I have secured open bearings or sockets 21, 2-1. Pivot pins 25, 25 are firmly secured near the opposite edges of the board 19 each pin positioned thereupon to project beyond the edge of the board and rest in the adjacent hearing 24. These pivot pins and bearings are so positioned that the central section is supported to permit registration of the ports 22 with the apertures 16. Near the upper and lower edgesof the ports 22 I bore holes in the trunk 20 and insert therethrough machine-threaded thumb-screws .26 and at corresponding locations in the chambers 16 and motor. Movement of lever'37 causes the connected valve 31 to vary the area of the port controlled thereby and change the speed of the winding devices. Movement of lever 36 causes the connected valve 30 to .vary the area of the port controlled thereby and limit the amount of direct air-tension in the action-devices. henthis valve completely covers its port, air-tension continues through the indirect passage and the regulator 28. Movement of lever 35 to reverse the position of the valves connected therewith draws the Valves 30 and 30 across their ports and thus entirely disconnects air tension from the action devices and moves the valve 31" to open direct communication with the chamber 18 and thus permit full tension to operate the music-sheet-winding devices at maximum speed. i

To remove the sections of the apparatus thus described the thumb-screws 26 are turned out of the bushings 27 and the central or tension-creating section is swung forward upon thepivot-pins 25 to a sufficient degree to permit lifting of the section out of the case. It may not be necessary to lift out the section in all instances for access to the rear thereof as the position shown in Fig. 5 will usually permit ordinary adjustments or repairs. Upon removal of the said section, however, the reservoir-chambers or tension-maintaining sections may be released from the supporting braces 14 and 141* and blocks 15 and 15 by turning out the screws 38 and removed by moving each chamber sidewise sufficiently to permit slipping of the nipples 17 from the flexible tubes 34. The chambers may'then be lifted out of the case. It will thus be seen'that disarrangement of the delicate adjustment of the tension-regulators .28 and 29 and the valveboxes 30 and 31 or connections therewith is not necessary for obtaining access to the strings of plate ofthe piano. If desired, this entire tension-regulating and controlling section may be removed as a unit by disconnecting the devices attaching the levers 35, 36 and 37 to the valves and releasing such screws as may have been inserted through the key-bed from the upper side thereof into the valve-boxes 30 and 31 bellows and secured to said supports, and a conduit or chamber communicating with said bellows and detachably secured to and in communication with said reservoir chambers.

16 1 insert interior and exterior threaded metal bushings 27. As shown in Fig. 4:, the

upper bushings may extend through the front side of the chambers and be received by the frame 16" and the lower bushings may-likewise be received by bolster-blocks .16 The rear surface of the extending ends the threaded bushings 27 an air tight communication may be established between the l chambers 16 and 16 by the trunk 20 with 'the pump-bellows of the central section.

I shall now describe the tension-regulating and controlling section. 'This section consists of the horizontally disposed chamber 18, action wind tension-regulator 28, motor wind tension-regulator 29, action valve-box 30, and motor valve-box 81.

The chamber 18 is formed by upper, lower, front and rear sides and end blocks preferably secured together to form a solid unit. Bolster-blocks may be located at different points in the chamber to prevent warping of the upper and lower sides. Openings 32 and 82 are located in the lower side to afford communication with the chambers 16 and 16 respectively, connection being made by means of nipples 33 and 17 and flexible tubes 34-. At either end of the upper side I place the valve-boxes 30 and 31 for controlling the different degrees of windtension for the pneumatically operable parts of the instrument. The boxes are removably secured in position upon the chamber and I prefer to construct them substantial enough to sustain the chamber 18 rigidly in position when they are in turn held to the under side of the key-bed. Other supports may of course be used if desirable. The specific construction of the valve-boxes 30 and 31 and the tension-regulators :28 and 29 do not constitute a part of this invention and I shall but briefly describe their functions,it-being understood that any desirable type of either of these devices may be used. Other constructions either of the instrument or the devices mentioned may warrant different positioning and manner of connection of the devices with chamber 18. The chamber 18 is supplied with ports 18 and 18 in its upper side and 18 and 18 in its lower side. In constructing the chamber the end blocks 18 and 18 are extended inwardly a suflicient distance to produce solid ends which may permit passages there through to open out in desired positions upon the upper and lower faces of the cham- I have shown an offset in the passages 18 and 18 to demonstrate the accommodation of regulators and valve-boxes with ports not correspondingly located.

The actionva1ve-box'30 is supplied in its lower side with ports positioned to register with the port 18 and the upper opening of passage 18 of the chamber and in its upper side with the port 30 for communication through the key-bed with the action devices located thcreabove. The motor valve-box 31is supplied in its lower side with ports positioned to register with the port 18 and the upper opening of passage 18 of the chamber and in its front side with the port 31 for communication in any desired manner with the music-sheetwinding windmotor usually located in the upper part of the 1nstrument. Controlling slide-valves are positioned in the boxes to be moved '1 over or from adjacent ports. The valves 30' and 30 1111 valve-box and. valve 31" vin valve-box 31 are connected for movement with the lever so that movement of the lever in one direction slides the valves and 30 over their ports and the valve 31 away from its port. Reverse movement of the lever causes reverse valve operation. Valve 30 is connected for movement with the lever 36 and preferably is held normally away from its port as shown in the drawings. Valve fil is connected for movement with the lever 37.

The tension regulator is connected with variable air-tension in the chamber 18 through the port 1 and causes air-tension regulated by the strength of the spring 528 (Fig. 2) in the passage 11. The construction and action of tension-regulator 25.) is similar to that of 28, being connected with variable tension through the port 18 and .causin re ulated tension in the passa e 18.

a b l a Operation of the treadles forces the sides 11 of the pump-bellows connected therewith tures 16 and 16 of the chambers, ports 22 and 21 of the trunk 20 into the pump-bellows past the check-valves 528. Air is prevented from returning through the ports 21 by the said valves 23 and is expelled by the collapse of the mmp-bell invs through the valveports 11. The same degree of air-tension is maintained in the chamber 18 as in the chambers 16 and 16 through the flexible connections 21-1 hereinbefrre descr bed. \Vith the controlling-valves in the positions shown in Fig. 2-, air-tension may be created in the pneumatic action devices (not shown) through the port 18 past both of the valves 80 a d 30 and through the port 30 without restriction and also through port 18" regulator 28. passage 18, past the valve 30 and so through the port 30, while tension may be created in. music-sheet-winding devices through the port 18, regulator 29. passage 18, past the tiondevices and regulatedtension in the:
